Quote:98j im gunna ask you a stupid question(might sound like it for you) but how do these machines level themselves is it automatic or do you the operator have a lever or rocker button you use to do it yourself. if so when do you know its level? all guess work?
thanks

Hello Aussiefarmer! Had any rain down your way??? Not a stupid
question at all....the leveling is automatic with a manual override.
On the 1670 that I have the privilege to run, the leveling is electric
over hydraulic, with two speeds. If the slope change is minor, the control unit opens the slower side valve; this keeps the leveling
smooth & even. If the slope change is greater, the high speed
valve is opened first, then as the leveler catches up, the high speed
side is closed and the slower speed finishes up. There are two switches for control.....one selects between auto or manual ....the
other switch tilts the machine left or right; it uses the high speed
valve. If you hit the switch to the right for example, regardless of
being in auto OR manual, the separator leans to the right. If you are
in manual, hit the switch to the right, the machine will go right until
you release the switch. If you are in auto, hit the switch to the right,
then release, then the machine is out of level and the auto control
starts it back. Manual is really an "off" position for the leveler. We
turn ours to manual (or off) when we get out on the road to transport ....keeps you from getting seasick when headed for the next field. You can use the manual override to "lead' the machine
when turning on a slope....for example, headed across a slope leveled out say about half way....to turn around and head back,
one technique is to start to turn (downhill) and get on the override
AHEAD of the auto control....that way, as the machine starts to come
out of the turn the leveler is ahead of the curve and is leaned into
the hill....release the override switch and let the auto control resume
control. One of our neighbors has a 1470 that came out of Washington that has the override switch moved from the control panel on the right to the hydro handle itself. That is a slick set up
because part of the deal on a turn like that is that you need a little
finesse on the hydro handle....start the turn downhill and the machine picks up speed, so you need to pull back a little to keep
the speed down to a point where the leveler can handle the change....if you try this too fast and come out of the turn with the
machine leaned the wrong way.....
well that's not good.
The override comes in handy when grabbing the platform off of the
transport cart.....missed the lineup by a whisker???....no problemo...
go to manual (off).....bump the leveler a little in the proper direction
and PRESTO
.....instant alignment.
Here is a demo shot....
manual position selected, then hit the direction switch to the left
until the separator is all the way over...
.....can't stay there too long ( don't want oiling problems in the motor).......select back to auto, and the machine comes back up
to level.
